Many 1-aryl-6-azauracils derivatives were prepared so far, among them the representation of m-substituted 1-phenyl derivatives is relatively poor. In this communication we report on the synthesis of the starting material - dicarbamate I, which was used for the preparation of some new 1-phenyl-6-azauracil derivatives II, containing simple nitrogeneous group in m-position. We focused also on the compounds III having two 6-azauracil rings mutually bonded in m-position to the benzene ring. These compounds can form hydrogen bonds simultaneously with two bonding centres of fitted substrate and so they can serve as model compounds for the interaction studies. From this type of compounds the dinitrile IIIa is known so far.
迄今为止,已经制备了许多1-芳基-6-氮杂尿嘧啶衍生物,其中代表着m-取代的1-苯基衍生物的表现相对较差。在本文中,我们报告了起始材料-双氨基甲酸酯I的合成,该化合物用于制备一些新的1-苯基-6-氮杂尿嘧啶衍生物II,其m-位含有简单的氮基团。我们还专注于化合物III,其两个6-氮杂尿嘧啶环相互连接在苯环的m-位。这些化合物可以同时与适配底物的两个结合中心形成氢键,因此它们可以作为相互作用研究的模型化合物。到目前为止,已知这类化合物中的双腈IIIa。
